WEBNov 16, 2022 · A power series about a, or just power series, is any series that can be written in the form, \[\sum\limits_{n = 0}^\infty {{c_n}{{\left( {x - a} \right)}^n}} \] where \(a\) and \({c_n}\) are numbers. The \({c_n}\)’s are often called the coefficients of the series. The first thing to notice about a power series is that it is a function of \(x\).

WEBNov 16, 2022 · To use the Geometric Series formula, the function must be able to be put into a specific form, which is often impossible. However, use of this formula does quickly illustrate how functions can be represented as a power series. We also discuss differentiation and integration of power series.

WEBA power series is a type of series with terms involving a variable. More specifically, if the variable is x, then all the terms of the series involve powers of x. As a result, a power series can be thought of as an infinite polynomial. Power series are used to represent common functions and also to define new functions.
